There is a new arrival in town. The newcomer hasn't had the best of luck when it comes to townsfolk, but it's in her very nature to seek out others. It is all she is; after all, a mirror that has no-one to look into it is useless. Very open and adaptable, she just wants friends that are willing to stick by her and let her stay around.

All the while, strange things happen all around as a pony appears to be able to trot anywhere he or she darned well pleases and go out and disappear without trace. Other than being dramatic and presenting him or herself as a master of disguise and a 'Magical Phantom Thief', he or she doesn't seem to steal anything of value, if at all... although the escapes tend to attract attention.

And he or she is tired of repeating the same phrase. Regardless of how strange, quick, or impossible the changes seem he or she is not a changeling.

And there is another player, looking for a traitor to her trust... but why is it so important to protect her associate from that traitor if they are going into the fray? And why explicitly exclude "the ponies"? Other than that it's obvious she's not one herself.

What's the relation? Is she working with the thief that can't seem to decide on a name? Against? Or are they all friends? One thing is certain; those who look close enough cannot help but see either a piece of their own reflection, or the gaping maw of the abyss.
